Sasa Sestic

Saša Šestić (born 24 October 1978) is a Bosnian-born barista from Canberra, Australian Capital Territory, and won the 2015 World Barista Championship

Sestic won the Australian Barista Championship run by the Australian Specialty Coffee Association in March 2015, at his seventh attempt.

Sestic pays attention to the freshness of his coffee beans. "I've looked at a calendar and seen when coffee will ripen in each country." "Seasonality is very important and we knew that the season would finish in Colombia from September to October." "Just like fruit and vegetables, when they're in season they taste great. It's the same thing with coffee."

As Australian champion, Sestic won the right to compete in the 2015 World Barista Championship held in Seattle, United States.

Sestic was selected into the final six, then won the finals round of four espressos, four cappuccinos and four signature drinks judged by sensory and technical judges plus a head judge.

The specialty coffee presented by Sestic contained a dash of Shiraz Viognier blended wine, ranked as an 'exceptional' wine, made at Clonakilla winery near Canberra.

Sestic owns Ona Coffee at four locations in Canberra's coffee districts:

• Manuka (The Lawns, Palmerston Lane)
• The Cupping Room (University Avenue)
• Fyshwick (Wollongong Street) including a wholesale bean outlet

And high road located in Dickson

Sestic represented Australia in Men's competition for Handball at the 2000 Summer Olympics in Sydney. He is the brother of Dragan Sestic.
